  • Need a pinout for c100 on 93-95 fbody 3.4l

    I need the connector pinout on c100 forward lamp harness connector for a 93-95 camaro/firebird with a 3.4l v6 if anyone has access to such a thing, I've tried finding it myself to no avail, I can find info for the connector, but no actual pinout that tells me what circuits are on it.
    I did manage to figure out that the oj wire is power to the ecm, which was the main thing I was looking for, but it also seems like the pink wires are power feeds to the ICM and various sensors, but I need to verify and figure out which ones. Also seems like the coolant temp sensor is on this circuit, and the fans as well if memory serves? So I definitely need to peg its pinout down.

    And just to clarify, no I can not just follow wires to their destinations, I have the engine harness, but no fwd lamp harness, nor the intent or need to get one(I am not using the engine harness in its factory application).

    this is for a 94 firebird, if it makes any difference.

    1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!

      Hmm, I may have mixed it up with something else, I will have to double check the colors, thats more or less what I expected to be on that circuit though, should help me sort things out at any rate, ty.

        if you get an exact year/model for the one you have now, i can pull that as well, to see if anything changed.

              Yeah that narrowed it down, though it doesn't show the orange pcm power wire in the diagram oddly. Also apparently my crank sensor power feed wire has some damage, I was reading 10 ohms =/, but at least the ICM power wire is good, lol. Didn't bother with the cam sensor wire since I will be running MPFI and not SFI anyway.
